c++ - error: Using directive refers to implicitly-defined namespace 'std'

Question

This is my code:

#include <iostream>
#include <cmath>

using namespace std;

double dobutok (double x);
bool input (int & x);

int main() {
    double x;
    while (true) {
        cout << "Enter x:
";
        cin >> x;
        try {
            if (x < 0 || x > 1) throw 1;
        }
        catch(int) {
            cin.clear();
        }
    }
}

and I get the error:

Using directive refers to implicitly-defined namespace 'std'

in CLion but in VS code everything works. Does anyone know the fix to this? Thanks
